A year ago this week, Chinese physicists launched the world's first quantum satellite. Unlike the dishes that deliver your Howard Stern and cricket tournaments, this 1,400-pound behemoth doesn't beam radio waves. Instead, the physicists designed it to send and receive bits of information encoded in delicate photons of infrared light. It's a test of a budding technology known as quantum communications, which experts say could be far more secure than any existing info relay system. They've kept the satellite busy.
Information has been'teleported' between two computer chips for the first time, a move that could lead to a more secure'quantum internet', researchers claim. Experts from the University of Bristol and the Technical University of Denmark were able to'instantly send the data' using a process called'quantum entanglement'. The information was exchanged without electrical or physical contact as the process allows these particles to instantly communicate over large distances. This is useful in quantum computing and networks as changing one particle will automatically change the other, say researchers from Bristol. The team say their study could lead to a quantum internet that'would ultimately protect the worlds information from malicious attacks'.
That might not sound like much, but in the quantum computing arms race, several groups are edging past one another as they aim to eventually make a universal quantum computer. A group of researchers at the Joint Quantum Institute has created a quantum simulator using 53 quantum bits, or qubits. Earlier this month, IBM announced a 50-qubit prototype, though its capabilities are unclear. With this 53-qubit device, the researchers have done scientific simulations that don't seem to be possible
IBM continues to push its quantum computing efforts forward and today announced that it will soon make a 53-qubit quantum computer available to clients of its IBM Q Network. The new system, which is scheduled to go online in the middle of next month, will be the largest universal quantum computer available for external use yet. The new machine will be part of IBM's new Quantum Computation Center in New York State, which the company also announced today. The new center, which is essentially a data center for IBM's quantum machines, will also feature five 20-qubit machines, but that number will grow to 14 within the next month. IBM promises a 95% service availability for its quantum machines.
IBM has announced a milestone in its race against Google and other big tech firms to build a powerful quantum computer. Dario Gil, who leads IBM's quantum computing and artificial intelligence research division, said Friday that the company's scientists have successfully built and measured a processor prototype with 50 quantum bits, known as qubits. Gil says it's the first time any company has built a quantum computer at this scale. IBM scientists have successfully built and measured a processor prototype with 50 quantum bits, known as qubits, the first time any company has built a quantum computer at this scale. The heart of modern computing is binary code, which has served computers for decades.
